It's a shame Wallace Labisky's work was never consolidated into one book. Labisky worked for years testing various components, including wads, to produce tighter patterns for long range shooting, primarily at geese. His work can be found virtually everywhere but is primarily found in Ballistic Products, Inc loading manuals- mostly those for the 10 and 12 guages. His work was so specialised it never recieved the attention of the "Blast and Stab" media but is none the less invaluable to those wanting tight, long range patterns.
